Mr. Olympia 2013 is underway and there are a number of qualified candidates who are going to try and unseat Phil Heath.
Heath, the two-time defending champion, is probably the biggest name in bodybuilding. He's just 5'9", but he has a nearly perfect physique.
While he is entering the competition as the favorite, there are a number of competitors who could knock Heath off the throne.
Who has the best chance? Read on to find out.
Kai Greene was the runner-up to Heath last year and also finished second to Heath at the 2012 Sheru Classic. He last won at the 2011 New York Pro.
Greene, at 38, is nearing the end of his career. But his dedication to training is impressive, and the results show. At 5'8", he's weighing in around 250 pounds, giving him an impressive amount of muscle mass.
It's going to be tough to unseat Heath, but Greene probably has the best chance. Proportionally, he is one of the biggest competitors in the field.
Look for Greene to put together a really solid showing and give Heath a serious run for his money.
Jay Cutler is one of the best bodybuilders in history and he's looking to win his fifth Mr. Olympia title.
It's been a rough few years for Cutler, as he hasn't won Mr. Olympia since 2011 and has battled injuries.
Cutler has been overtaken by Heath in terms of popularity and success, and at 40-years-old, the chances for Cutler to get back to the top of the sport may be running out.
The biggest question is which Cutler is going to show up.
Will he come in tip-top shape, channeling the form that made him victorious four times and finish in the top-two eight times? Or will he come in like a bodybuilder who has missed a year, out of shape and out of contention?
It would be unwise to write off Cutler, given that he's been in the game for so long. It might be harder to unseat Heath, who is in his prime, but Cutler, assuming he comes in great shape, has a chance to get back to the top of the field.
Dexter Jackson is one of the oldest participants in this year's Mr. Olympia, but he has the experience and savvy to pull off an upset.
He won the Sandow Award in 2008 and has four Arnold Classic victories and a Masters Olympia victory on his resume.
He's not as big as the other competitors, but he has a great physique and knows what to do to win the judge's favor.
It would be an upset, but with his know-how, Jackson could attack Heath's weaknesses and pull off the victory.
